ppc32 _SDA_BASE_

[Alan Modra]

glibc uses a ld -r stage to build crt1.o, and due to stupidity on my
part ld -r was providing values for _SDA_BASE_.

$ readelf -a /home/alan/toolchain/lib/crt1.o | grep _SDA_BASE_
00000000  00001401 R_PPC_ADDR32      00000000   _SDA_BASE_ + 0
    20: 00000000     0 OBJECT  LOCAL  HIDDEN  ABS _SDA_BASE_

Resulted in failure of gcc.dg/980827-1.

	* emultempl/ppc32elf.em (after_allocation): Don't call
	ppc_elf_set_sdata_syms when relocatable.
